摘要
This application relates to a cylinder throw-off/throw-on controller for a lithographic rotary press having a plurality of printing units each having a pair of opposed blanket cylinders which are movable between a printing position in which the blanket cylinders are disposed so as to be in contact with a paper web posing therebetween, and a non-printing position in which the blanket cylinders are spaced from said paper web and a paper feed unit adapted to supply a paper web of a paper roll to said printing units and to splice the leading end of a new paper roll to the paper web of the currently used paper roll in response to a paper splicing signal which is issued when the currently used paper roll runs out, the cylinder throw-off/throw-on controller comprising: i) a cylinder throw-on timer provided for each of the printing units, wherein said cylinder throw-on timer is activated in response to the paper splicing signal and is adapted to issue a cylinder throw-on signal after a predetermined period of time; and ii) cylinder throw-off/throw-on means for a) simultaneously moving the blanket cylinders from the printing position to the non-printing position in response to the paper splicing signal and b) for sequentially moving the blanket cylinders from the non-printing position to the printing position in response to the cylinder throw-on signal, from the furthest-upstream printing unit, with respect to the paper feed unit toward the furthest-downstream printing unit.
